August 21, 1949 - a damaging M8.1 #earthquake (one of the largest ever recorded in North America) struck off #HaidaGwaii. Shaking was so strong that it was hard to stand. Felt across most of #BritishColumbia, parts of Alberta, WA, Yukon and Alaska www.earthquakescanada.nrcan.gc.ca/historic-his... ⚒️🧪
77 years ago tonight - a M8.1 #earthquake off #HaidaGwaii ruptured a 500-km-long segment of the Queen Charlotte Fault ("Canada's San Andreas Fault"). The average slip along the #fault was ~5 m. Shaking was so strong that it was hard to stand. More than 100 aftershocks were felt on Haida Gwaii. ⚒️🧪🇨🇦
There was a little shake on the west coast of Graham Island that USGS posted about (and Emergency BC also mentioned) but curiously NRCanada does not have listed

Great question - thanks! It is a complicated region, with a number of faults (and different types). There is a transform fault (QCF) that extends from southeast AK to south of Haida Gwaii and the Haida Gwaii thrust fault (e.g., the 2012 M7.8 earthquake). Research is still underway - so "other"?
Interesting that USGS lists the major fault types - not sure why Haida Gwaii is listed as "other" but suspect it is due to recent studies about the newly emerging subduction fault (?) paging @earthquakeguy.bsky.social
What an incredible technology via Andriod phones - built in accelerometers pick up seismic waves and send out alerts, in an area without an early warning system #earthquakes @earthquakeguy.bsky.social
It's almost as if it's not the federal government that is the problem so much as the weak-ass business case for new pipelines.

Did you feel shaking on #HaidaGwaii at 1:35 p.m. today? That was a M4 #earthquake located off the east coast, 31 km from Daajing Giids and 37 km from Port Clements. Details: www.earthquakescanada.nrcan.gc.ca/recent/2026/... Please report shaking: www.earthquakescanada.nrcan.gc.ca/dyfi-lavr/fo... ⚒️🧪
Another #earthquake on Haida Gwaii, shook longer! Maybe 4m ish? 13:35 #haidagwaii
Feels like a bunch of little earthquakes going through Haida Gwaii today - family + neighbours were buzzing about this morning (May 10 around 11:26 am PST) and then another at 3:45 pm PST that was mentioned by USGS. Just now all my windows creaked + floor flexed briefly
Ooo little earthquake about 45 min ago, what an odd roll #haidagwaii #earthquake looks like a 4.1m on the west coast by tasu inlet
Turns out the residential school denialist movement is really just a handful of fired or retired academics who created an email group to create denialist content that is being boosted by far-right media, think tanks, and politicians to attack truth and reconciliation: thetyee.ca/News/2026/05...

For the @nytimes.com, I covered a massive landslide in Alaska last August that generated the second-largest tsunami wave on record. Here's the story, in video form.

Canada's Quakes of 2025 The Haida Gwaii region is one of Canada's seismic hotspots. During 2025, 1248 #earthquakes (M0.7-4.8) were located here (few were felt). Note that several M7-8 earthquakes have occurred here during the past 100 years. www.earthquakescanada.nrcan.gc.ca/historic-his... ⚒️🧪🇨🇦
Serious situation on Haida Gwaii - the north end of the island is completely cut off from the south end. The hwy is washed out at jungle beach, sections of pavement gone. The Yakoun River is flooded + the back road is impassable at several points. No way to get to ferry, no freight delivery
Hwy 16 on Haida Gwaii has been closed due to a washout from extensive flooding at Jungle Beach. They are waiting until first light tomorrow to assess the damage.
Another year, and another 6000+ earthquakes recorded across #Canada. Stay tuned over the next week or so to learn more about Canada's #earthquakes of 2025... the largest, the most widely felt, the swarms, the science. Where and why? Feel free to ask questions (responses may be delayed a bit). ⚒️🧪🇨🇦
Not sure what is happening in Port Clements tonight, two long rumbling sequences, almost like a rock slide? At 10:15 and 10:21 pm. Too late for blasting, what the heck. The last one rattled the house windows

NOAA cut funding to the Alaska Earthquake Center, directed by my friend Mike West. As a result, seismic monitoring by nine stations in Alaska tracking tsunami-causing earthquakes will go offline by the end of the month. This endangers people in Alaska, Hawaiʻi, and other parts of the Pacific.
This lab is key for tracking deadly waves. Its sensors are about to go offline.
